SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS.

According to the Significant Wildland Fire Potential Outlook by the
National Interagency Fire Center on September 1st, the potential for
significant wildland fires across Deep South Texas is normal for
September through December 2019. The latest observed Fire Danger Map
from the Texas Inter-Agency Coordination Center (TICC) on September
20th indicated a high to very high fire danger across northern and
western portions of Deep South Texas with a low to moderate fire
danger across the remainder of Deep South Texas. The latest Keetch-
Byram Drought Indices (KBDI) were 500 to 600 over Zapata, Jim Hogg
and Starr counties, 400 to 500 over Brooks and Hidalgo counties, and
300 to 400 over Cameron, Willacy and Kenedy counties. Residents of
Deep South Texas, especially across Zapata, Jim Hogg, Starr, Brooks
and Willacy counties, are urged to take extra precautions when
conducting any outside burning, and should contact county officials
for any scheduled burning. Residents are also reminded that fire
danger can change quickly from one day to another as winds and
relative humidity values vary.

AGRICULTURAL IMPACTS.

According to the United States Department of Agriculture and Texas
Agrilife Extension Service Agents...isolated to widely scattered
showers provided short to very short soil moisture levels. Starr
County reported 1 to 2 inches of rainfall while Zapata County
reported light rainfall amounts. Pasture and rangeland conditions
were in fair to poor condition. Supplemental feeding continued for
livestock and wildlife. Irrigated crops were in good condition.
Zapata County producers were still hauling water for livestock.

(TCEQ)...there are 32 cities or water supply entities that are under
voluntary or mandatory water restrictions. There are 8 Public Water
Supply entities in Cameron county, 13 in Hidalgo county, 6 in Starr
county, 3 in Zapata county and 2 in Willacy county. All water users

from September 26th through September 30th.

The long range climate outlook for Deep South Texas through December
2019...derived from guidance from the National Weather Service and
the Climate Prediction Center...indicates that generally above
normal temperatures and equal chances of above normal/near
normal/below normal rainfall are expected for Deep South Texas
through the fall of 2019 into early winter 2019. The latest seasonal
drought outlook from September 19th indicates that drought will
persist across extreme northern and western portions of Deep South
Texas for the rest of September through December 2019.
